All That I Am

Who am I?
What am I?
You ask these things like they matter.
Does it really matter?
As long as I do my duty?
To some,
I'm a warrior,
As fierce as Saturn's hold,
To others, a healer,
The guardian of life.
To a few,
I'm shy and timid,
But I mean well,
And will always be loyal to the end-
But is that what I really am?
Does this body even make me - me?
My long dark green hair,
My violet-brown eyes.
If they were to change,
Would I be the same?
I know my own name,
And that is enough for me;
That is all.
I am Setsuna, guardian of Time,
And that is all I am.
